Eaton 9PX3000RTN‑L – Online UPS 3000 VA 2700 W 120 V

Overview

The Eaton 9PX3000RTN‑L is a rack/tower online double‑conversion uninterruptible power supply (UPS) engineered to deliver consistent, conditioned AC power and battery backup for critical 120 V IT infrastructure loads. It is deployed by data center engineers, network architects, and facilities teams to maintain uptime for core servers, storage systems, aggregation switches, and virtualization hosts, isolating loads from utility disturbances such as sags, brownouts, and surges. The online double‑conversion topology actively rectifies and regenerates output voltage and frequency, ensuring a stable true sine‑wave supply throughout utility irregularities.

This unit is rated 3000 VA / 2700 W with a 0.9 power factor and provides tight ±1 % steady‑state voltage regulation, supporting medium‑density rack loads typical of enterprise convergence zones and small data halls. It features a mix of receptacles—including six NEMA 5‑20R and one L5‑30R outlet—to accommodate diverse rack equipment. The UPS uses lithium‑ion batteries with integrated battery management (BMS), enabling longer life and reduced weight versus traditional lead‑acid systems, and supports up to four extended battery modules (EBMs) for runtime expansion.

Deployment is in a 2U rack/tower form factor, including a 4‑post rail kit for standard 19‑inch enclosures, making it suitable for core racks, consolidation points, and dedicated UPS cabinets. The unit ships with a Gigabit SNMP/Web network card installed in the Mini‑Slot expansion port, providing remote monitoring, event logging, and integration with Eaton’s Intelligent Power Software Suite for controlled shutdowns and alerts. Local diagnostics are available through a graphical front panel with programmable menu.

Communication options include USB (HID), RS‑232, and Ethernet via the network card, along with remote ON/OFF and relay interfaces. The UPS also incorporates an internal bypass for maintenance and service workflows, which allows load continuation during local servicing.

A practical deployment example is powering a consolidation rack containing virtualized hosts, SAN storage, and core network switches. During utility power loss or severe voltage anomalies, the UPS’s online topology maintains clean, stable power, while extended battery modules provide additional runtime for transitioning to standby generators or controlled service shutdowns, minimizing risk of data loss and service disruption.

This unit is not suitable for small branch closets, desktop environments, or simple rack edge deployments where lower‑capacity line‑interactive UPS models suffice. Additionally, environments requiring integrated maintenance bypass cabinets or modular hot‑swappable power modules may consider larger, more serviceable UPS families.
